Any questions about the Rolex GMT Master II Two Tone 126713GRNR — The Zombie Black Jubilee?
Your designated concierge is always available to talk watches!
Here’s what most people don’t say upfront about the Rolex GMT Master II Two Tone: it’s not just another Rolesor GMT. Reference 126713GRNR debuted at Watches & Wonders Geneva in April 2023 with two things no precious-metal GMT-Master II had ever done before — simultaneously. First time a Jubilee bracelet went on a gold-and-steel GMT in Rolex history. First grey-and-black Cerachrom bezel in the GMT line, full stop. Neither of those is a footnote. They’re the reason this specific reference gets attention when every other two-tone GMT just sits there. We carry authenticated examples and know this reference well. Browse our current GMT inventory or reach out directly — we’ll tell you what we actually have available today.
The Rolex GMT Master II Two Tone — reference 126713GRNR — arrived with two documented firsts. First was the grey-and-black bezel. Rolex codes it internally as GRNR, for Gris-Noir — French for grey-black. Producing it required a two-stage ceramic sintering process: two distinct colours fired into a single Cerachrom insert with no seam, no fade, no imperfection between them. No GMT had ever worn that bezel before this watch. Second was the Jubilee bracelet on a precious-metal GMT. Every Rolesor and full gold GMT-Master II before the 126713GRNR wore an Oyster bracelet. The Jubilee had stayed on steel sport GMTs only — the Pepsi, Batman, Batgirl, Destro. The Rolex GMT Master II Two Tone changed that permanently.
Collectors named it “Zombie” almost immediately. Grey and black — grey like the undead, black like night. The nickname follows the same colour logic behind every GMT name: Pepsi (red-blue), Batman (black-blue), Sprite (black-green), Rootbeer (brown-black). When a reference earns a nickname that fast, the market has already decided it matters. That’s worth keeping in mind when you think about long-term value.

The Rolex GMT Master II Two Tone is built on a 40mm Oyster case in Rolesor — Rolex’s combination of Oystersteel and 18K yellow gold. Gold appears on the bezel, crown, crown guards, and alternating Jubilee bracelet links. The steel is 904L Oystersteel, Rolex’s proprietary alloy. It’s harder and more corrosion-resistant than the 316L steel most other watch brands use, and it holds a finer polish. You can see it on the brushed-and-polished case surfaces — the transitions between finishes are sharp and stay that way through years of daily wear.
The five-link Jubilee bracelet closes with an Oysterlock folding clasp and Rolex’s Easylink system — a 5mm rapid extension built into the clasp itself, adjustable without any tools. A practical feature on a $20,000 watch. According to Rolex, every case is individually pressure-tested before leaving the facility — not batch-tested, every single unit.
On the Rolex GMT Master II Two Tone, the Jubilee bracelet does something the Oyster bracelet can’t — it makes this watch genuinely work in dressed-up settings. Wear the Oyster-braceleted Rootbeer to a business dinner and it reads sport. The Rolex GMT Master II Two Tone on its Jubilee reads like a deliberate luxury watch, not just a travel tool. That’s exactly why buyers who need one watch across all contexts keep landing on the Zombie specifically, rather than its two-tone siblings.
The Rolex GMT Master II Two Tone runs the Calibre 3285, which replaced the Calibre 3186 in all GMT references from 2018 onward. The improvement is real and practical. Power reserve jumped from 48 to 70 hours — the difference between a watch that stops on Sunday and one that’s still running Monday morning after a weekend off the wrist. Accuracy is certified at ±2 seconds per day under Rolex’s own Superlative Chronometer standard, which is stricter than COSC’s external limit of -4/+6 seconds. That certification is applied to the fully cased watch, not the bare movement on a bench.
The Parachrom hairspring delivers ten times the magnetic resistance of a standard alloy spring. The Chronergy escapement improved energy efficiency by around 15% over the previous architecture. These details matter because they directly affect how the Rolex GMT Master II Two Tone performs day to day — not on paper, on the wrist.
The GMT complication lets you adjust the local hour hand independently in one-hour steps when crossing time zones, without stopping the movement or disturbing the minute hand. The 24-hour GMT hand keeps tracking home time continuously. The grey half of the bezel marks AM hours, the black half marks PM — so you read the reference time zone instantly, day or night, without any mental math involved.
Not everyone. That’s the honest starting point. The Rolex GMT Master II Two Tone is a specific watch for a specific kind of buyer, and knowing whether that’s you saves a $20,000 mistake.
If you cross time zones regularly and want to stop checking your phone at dinner to know what time it is back home — this is the watch. Grey half of the bezel means day, black means night. One glance. Done. That’s a precision instrument, not decoration. It’s genuinely useful if you live between two time zones. Genuinely pointless if you don’t.
If you need one watch that works in every room you walk into — boardroom, airport, weekend dinner — the Jubilee bracelet is what makes the Rolex GMT Master II Two Tone different from its siblings. Put the Rootbeer in a business meeting and it reads as a sport watch someone forgot to change. The 126713GRNR on its Jubilee reads as a deliberate choice. That distinction matters to certain buyers and doesn’t to others. Know which one you are before you spend the money.
If you’re buying with the next ten years in mind rather than the next six months: this reference launched in 2023 with two documented firsts and hasn’t been priced like it peaked yet. First-generation references with genuine collector significance, bought near retail before the narrative gets fully priced in — that’s historically been the right call. Not as a trade. As a watch you wear and hold.
Where it doesn’t fit: full steel sport aesthetics belong to the Batman and Pepsi. Maximum short-term appreciation belongs to the steel Daytona — forty years of track record there. Something you can wear rough without a second thought — that’s the Submariner. The Rolex GMT Master II Two Tone is for a specific buyer. If you’re reading this paragraph and nodding, you probably already know which one you are.
When the 126713GRNR launched at Watches & Wonders 2023, secondary market prices hit around $25,000 on opening hype. By late 2023 they’d pulled back toward retail — around $19,000 to $21,000. Through 2025 and into 2026, the Rolex GMT Master II Two Tone has been trading in the $20,000 to $26,000 range depending on condition and papers. That’s near retail for a watch with two documented firsts attached to it. Compare that to the Batman or Pepsi, where you’re paying 30 to 80% above retail because of AD waitlists that run years. The Rolex GMT Master II Two Tone doesn’t carry that scarcity premium — you can actually buy one at a fair price today, which is genuinely unusual for a reference with this kind of collector narrative.
It’s also worth knowing what drives price differences within the 126713GRNR market. Condition is the biggest factor — an unworn example commands a clear premium over a lightly worn or polished piece. Documentation is the second factor: full box and papers (warranty card, inner and outer box, hang tags, spare links, bracelet tool) will add meaningfully to both sale price and ease of resale. Serial number dating is the third — an early production example from 2023 is a different proposition than a later run. All of that is verifiable, and we verify it before listing.
Papers matter. An unworn example with the full set holds value better and sells faster than an unpapered piece. All watches at Crown Watch Group are authenticated and documented before they’re listed. No grey market, no undisclosed service history, no gaps in documentation.
Grey and black bezel. Grey like the undead, black like night — it maps instantly. GRNR in the reference number is Rolex’s code for Gris-Noir, French for grey-black. The nickname arrived within weeks of the April 2023 launch and stuck. Same logic as Pepsi (red-blue), Batman (black-blue), Sprite (black-green). When a watch earns a name that fast, the market has already made its decision.
Near-retail pricing, two documented firsts in the GMT line, less than three years old, and a strong collector narrative already built. If that combination makes sense to you — yes. It’s a long-term hold, not a flip. But for buyers who want a versatile precious-metal GMT without paying a scarcity premium, there’s nothing more compelling in the current catalogue at this price.
Gris-Noir. French for grey-black. That’s Rolex’s internal colour code for the bezel on the Rolex GMT Master II Two Tone — and an accurate description of exactly what the bezel is.
Power reserve went from 48 hours to 70. Chronergy escapement improved efficiency by 15%. Parachrom hairspring with ten times the magnetic resistance of a conventional alloy. Both are Superlative Chronometers — but the 3285 is a generation ahead in every practical measure, and it’s what’s running inside the Rolex GMT Master II Two Tone.
